Transcatheter aortic valve implantation (TAVI) offers a less invasive treatment alternative to surgical aortic valve replacement for high-risk patients. Although the procedure can be performed at low risk, life-threatening complications may arise in single cases during or even months after the procedure. Here, the details are presented of two patients who underwent TAVI by a transfemoral approach with Medtronic CoreValve prostheses and suffered myocardial

ischemia months later. The patients’ anatomy with small aortic root, narrow sinus of Valsalva and small distance between the annulus base and coronary arteries and/or the relative oversizing of the CoreValve prosthesis with a high positioning may have contributed to this late complication. Hence, caution is mandatory in this type of patient, with exact pre-procedural planning and close follow up required.
